To a/ZZ whom it may concern:

Be it known that I, RUPERT ELwooD HAR- EYMAN, a citizen of the United States, residtheV county of Jeersonl ment are to provide aportable sash-lock,

simplicity of construction and operation, ineXpensiveness, effectiveness, and to provide a sash-lock that will lock either or both sash either in a closed or partly-open position. These objects I attain by means'of the device illustrated in the accompanying drawings, in which- Figure 1 is an elevation showing the lock in position; Fig. 2, a detail view of a modification; Fig. 3, an edge view, and Fig. 4a horizontal section on line A B of Fig. 1.

Similar reference-numerals refer to similar parts throughout the several views of the drawings.

' The integral legs and handles 1 and the base-plate 2 constitute the body of the device. The legs 1 are pivoted on base-plate 2 by means of rivets 4, and the feet 3 are pivoted to the end of legs 1 by means of rivets 5. A wire spring 7 is coiled about and held in position by a rivet or post 6, secured in base-plate 2.

8 represents the portion of the windowframe in which the sash slide.

9 is the top cross-rail of the lower sash, and 10 the bottom cross-rail of the upper sash.

11 is the window-stop.

The free ends of legs 1 beyond rivets 4 eX- tend outward and serve as handles 15 for manipulating the device. These handles are somewhat turned in toward'each other, so that the inner portion is curved and forms a groove adapted to receive the free ends of spring 7. Concentric with rivets 4 are arranged gear-teeth integral .with legs 1 and intermeshing, which serve to preserve the symmetrical relation of the legs with relation-to base-plate 2. It will be seen that the free ends of spring 7 pressing against the handle portions of legs 1 have a tendency to force said handles apart, and this results in bringing the feet 3 at the free ends of legs 1 toward each other. The feet 3 being pivoted on rivets 5 always accommodate themselves to the vertical flat surface of the upper sash, against which they press, whatever may be 'be made rights and lefts.

the angular relation of the legs. The base 2 is adapted to press against the inner edge of stop 11, against which the lower sash slides, and its extensions are bent at an angle at `each-end, adapting themto rest upon or other- `wise engage the top-'of the top cross-rail 9 of the lower sash. Both extensions of baseplate 2 yare bentatan angle in order that the devicemay be used on either side of the window as may be most convenient and need not 12 is the partingstrip, 13 the side rail of the upper sash, and

14 the sash-cord.

rlhe manner of usingmy improved sashlock will now be understood. The handles are grasped with the thumb and first linger and pressed together against the action of spring 7, thus spreading feet 3 apart and thereby decreasing the distance between feet 3 and the bearing-surface of base-plate 2. In this condition the lock may be placed against the surface of window-stop 11 and parting-strip 12 with the feet pressing against the inner'surface of the side rail 13 of the upper sash and the serrated bearing-surface of base-plate 2 engaging the surface of the window-stop, against which the lower sash slides. The angular end of the extension of plate 2 is placed upon the top rail 9 of the lower sash if said sash is to be kept closed and the handles are released. The upper sash is thus secured in whatever position it may be against movement in either direction, and the lower sa sh is held down at the same time. If it is intended to have both sash partly open before placing the lock in position, the upper sash is drawn down to the required position and the lock placed against it at a suitable distance above the lower sash. The upper sash will now be locked in that position, and the lower sash may be raised till the top rail engages the angular extension of plate 2. It will be understood that placed either by the right hand orthe left hand on either side of the window by simply reversing it and placing the corresponding the device may be angular extension of plate 2 upon the top i rail 9 of the lower sash.

This sash-lock is portable, not being fastened to the sash or to the window-frame, and is therefore adapted for use by tenants and others who are not permanently located and have occasion to change their Adomicile more or less frequently.

Having thus described my invention so that any one skilled in the art pertaining IIO *www

thereto may male and use it, do not desire to claim spreading legs and pivoted feet broadly in a device of this class, because I am aware that these have been used; but

I claim l. A portable Window-sash lock comprising in combination a base-plate, a pair of diverging legs and integral handles pivoted on said base-plate, a spring pressing against and adapted to spread said handles and converge said legs, a pivoted foot on the end of each leg adapted to engage the sash, said baseplate provided with an extended portion disposed in a plane at right angles to the plane of said legs having its outer surface serrated or roughened and adapted to engage the Window-stop and having its extended ends bent at an angle and thus adapted to engage the top rail of the lower sash, substantially as specified.

2. As an article of manufacture, a portable sash-lock, comprising a base-plate, means for engaging the inner face of the side rail of' the upper sash and securing it against movement in either direction consisting of spreading legs pivoted on said base-plate and feet pivoted on said legs, corresponding means for engaging the Window-stop provided. by said base-plate, and means for engaging the top of the lower sash and securing it against upward movement provided by extensions of said base-plate, substantialbT :is speciiied.
